User Manual V1.3-2024-01-25

6.2 Connecting the PE Cable

• The PE cable connected to the enclosure of the inverter cannot replace the PE cable
connected to the AC output port. Both of the two PE cables must be securely connected.
• Make sure that all the grounding points on the enclosures are equipotential connected
when there are multiple inverters.
• To improve the corrosion resistance of the terminal, it is recommended to apply silica gel
or paint on the ground terminal after installing the PE cable.
• Prepare the PE cable according to the cable specifications and
according to the following figure.

L=L1+2mm

6.3 Connecting the AC Output Cable

• Do not connect loads between the inverter and the AC switch directly connected to it.
• The Residual Current Monitoring Unit (RCMU) is integrated into the inverter. The inverter
will disconnect from the utility grid rapidly once it detects any leak current over the
permissible range.
Select and Install RCD depending on local laws and regulations. Type A RCDs (Residual Current
Monitoring Device) can be connected to the outside of the inverter for protection when the DC
component of the leakage current exceeds the limit value. The following RCDs are for reference:
300 mA.
